IMPROVEMENT IN REFRIGERATORS.

Specification forming part of Letters Patent No. 130,635, dated August 20, 1872.-

Specification describing a new and Improved Refrigerator, invented by BENJAMIN NATHANIEL HATcHEsoN, of Green Point, in the county of Kings and State of New York.

Figure 1 represents a sectional elevation of my improved refrigerator. Fig. 2 is a detail vertical section on an enlarged scale, showing the new form of joint; and Fig. 3 is a similar section, showing the old form of joint.

Similar letters of reference indicate corresponding parts.

This'invention has for its object to improve the construction of retri erators or ice-bore.

es in such manner that the escape of the coalfilling over the top of the sheetanetal lining will become impossible, as well as the entrance of air and moisture from within into the space containing the coal or other non conducting filling. The invention consists in the use of strips or laths, placed-against the flush inner edge of the refrigerator top, and overlapping the face of the sheetmetal lining.

In order to fully understand the difference between my invention and the device now in use, I will first describe the latter with reference to Fig.3 of the drawing. In this A is the outer box; B, the inner box; 0, the intermediate space, containing coal-dust or equivalent non-conducting material. Dis the top piece, nailed upon A and B. E is the sheetlnetal lining, bent over the top edge of B, and then nailed down together with the top D. This is the manner in which ice-boxes are now made. The joints between the bent upper piece of the sheet-metal lining and the top can never be made sufficiently tight to prevent the escape of coal-dust during the transportation of the article. While the latter is in use air 'i'rom [Within can also enter the space (3,

moistening the coal or other filling, and eating away the wood-work. In order to prevent these defects I do not lap the lining E over the top of B, but continue it upward along the I edge of the top D, which is rabbeted to receive Instead of rabbeting the top D for the reception of the lining, the strip F may as well be rabbeted with substantially the same results.

Having thus described my invention, I claim as new and desire to secure by Letters Patcut- In a refrigerator, the combination, with the upper part of the lining E, applied as dedescribed, ot' the top 'D and strip F, all constructed substantially as set forth.
